I am taking Geometry for my summer credit and need help understanding vocabulary so if you could simplyfy that would help
here is what i got

Median-of a triangle is a segment from the vertx tothe midpoint of the opposite side

altitude-perpendicular segment from a vertex to the opposite side or to the line that contains the opposite side

centroid of a a triangle- point always inside the triangle point of concurrency if the medians of a triangle

orthocenter-lines containing the altitides are concurrent and intersect at a point

perpendicular bisector-is a line that is perpendicular to a side of the triangle ar the midpoint of the side

circumcenter-point of concurrency of the perpendicular bisectors of a triangle

incenter of a triangle-point of concurrency of the angle bisector

reminder: if you can simplyfy these definitions or make them clearer in any way that would be a great help thank you

I need a formula using polar form i.e. (r1, theta 1) and (r2, theta 2). The more simplified the formula is the better :)
oh and heres a trig identity that may be useful:
cos(theta 1)cos(theta 2) + sin(theta 1)sin(theta 2)= cos(theta1-theta2)
